“Don’t get us mixed up”, said a sultry Khloe to the camera, clearly poking fun at the duo’s matching platinum blonde locks.

Fans quickly realised that they weren’t being given an introduction to either of the reality stars’ baby bumps, as Kylie went on to reveal: “We are gonna try on the new In Love With The Koko collection for you guys.”

In the video, both sisters were only shown from the chest up, with Khloe’s black top unzipped low enough to see her bulging breasts.

Kylie was again wearing an oversized black jacket, which completely disguised the shape and size of her body, but fans commented that her face was a tell-tale sign that she is “pregnant.”

“Y’all look pregnant”, said one blunt follower.

“Aww you can tell Kylie is Prego her face is getting wide…we just want to know!!” urged another.

Someone else claimed: “Kylie’s face gives away her pregnancy”

“Is this the part where we’re still pretending Kylie isn’t pregnant?” asked another.

“Show the belly”, begged another fan, followed by heart-eye emojis.

Khloe’s latest video comes after she showed off plunging cleavage in a Snapchat selfie – but cropped out her “baby bump” as she pouted for the camera.
